Thoughts on TMPFS no longer being considered "highly experimental"

[David O'Brien]

Hi KIB,
Thanks for the list of issues you know about -- I don't believe we have
PRs covering those.

I've been following the patches you've been passing to Peter Holm as part
of this thread.  Seems good progress has been made in fixing some of the
issues.

Quite true, but is there any other subsystem where we know we have bugs
and have put up such a scary warning?

I've never used ZFS on i386, but I understand it is trivial to panic
with out-of-the-box settings.  We don't print a dire warning for ZFS
usage on 32-bit platforms.  So I'm not sure we should keep it for TMPFS.

I cannot tell from your response if you're OK or against removing
the warning.  [especially if your patches pass the Peter Holm test
and remove some of the bugs]
